About the MACGREGOR 21
Called the Venture 21 from 1966 - 1979
Designed by Roger Macgregor and built by Macgregor Yacht Corp. (USA) from 1980–1985, the MacGregor 21 is a lightweight, trailerable sloop known for its ease of handling. With a displacement of 1175.0 lb and a LOA of 21.0 ft, it serves as an accessible entry point into sailing, though its age and composite construction require diligent maintenance.
- Best for:
- This boat suits coastal cruisers, weekend warriors, and single-handers who prioritize trailerability and low maintenance costs over heavy offshore performance. Its light displacement and manageable size make it ideal for sailors seeking a portable, easy-to-store vessel for local waters.
- Bluewater capability:
- With a capsize ratio of 2.59 and a comfort ratio of 7.29, the MacGregor 21 is not designed for extended offshore passages but is capable of protected coastal cruising. Its light displacement of 1175.0 lb and fin keel configuration prioritize speed and trailerability over heavy-weather stability.
- Comparables:
- Comparable boats include the Catalina 22 and O'Day 23, which share similar dimensions and roles as popular trailerable cruisers from the same era. Unlike these heavier fiberglass designs, the MacGregor 21 distinguishes itself with its composite construction and significantly lower displacement.
